Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.

Yes it is smaller in terms of diameter. Explanation: 25 gauge refers to a needle having an inner diameter of 1/25" (1/25 inches) and 22 gauge refers to a needle having an inner diameter of 1/22" (1/22 inches). Thus the 25 gauge needle has a smaller inner diameter than a 22 gauge needle.
Diameter
Yes, a 30 gauge needle is larger than a 31 gauge needle. In the gauge system, a higher number indicates a smaller diameter, so a 31 gauge needle is thinner than a 30 gauge needle. Therefore, the 31 gauge needle would be the smaller of the two.
A 25-gauge needle is smaller in diameter than a 23-gauge needle. The larger the gauge number, the thinner the needle, so a 25-gauge needle has a smaller lumen compared to a 23-gauge needle. This means that for tasks requiring finer needles, such as pediatric or cosmetic procedures, a 25-gauge needle would be preferred.
The gauge of a needle is determined by its diameter, with smaller gauge numbers indicating larger needle diameters. Thicker medications or fluids may require a larger gauge needle for administration, while thinner medications may be better suited for smaller gauge needles to minimize discomfort for the patient.
The larger the wire gauge, the smaller the diameter. 12 gauge is bigger than 14 gauge.
The smallest gauge needle that I'm aware of is 22g. But no one will pierce you with anything less than 20g, and that's usually in the nose. But, the standard size piercing needle is around 16-12g, but you can make a request to be pierced at a larger gauge, if there's sufficient flesh for it to go through.
A needle with a size of 0000 (4 zeros), also known as a 0000 gauge needle, has the largest diameter. These needles are typically used for thick materials like leather or heavy-duty fabrics.
The width of a needle varies depending on its type and purpose. For example, a standard sewing needle typically has a diameter ranging from about 0.5 mm to 1 mm. In contrast, medical needles, like those used for injections, can have widths (gauge sizes) that range from around 0.2 mm to 1.5 mm or more. Overall, needle width is specified by its gauge, with a higher gauge number indicating a thinner needle.
It could be used as long as the needle length is approximately 1 1/2 inches long so that it reaches the muscle tissue. The flu vaccine injections are given IM (intramuscularly) except if it is the new intradermal type of vaccine, which has its own delivery system with a very tiny needle injected into the layers of skin. The typically sized needle for IM administration of medication is a 22-25 gauge, 1 1/2 inch IM needle. 23 gauge is slightly larger around than a 25 gauge, so it is possible you could feel it slightly more when inserted. A 23 gauge needle has an outer diameter of 0.02525 inches. A 25 gauge needle has an outer diameter of 0.02025 inches. As long as you are able to correctly measure the proper dosage, it could be used.
